invention relates to an im rovement in te egraphy and has more speciareference mitting circuit.

to the receiving device of a telegraphic s stem.

The invention has more special re erence to a receiving device adaptedto expand or inflame through-theincoming im ulses a gaseous medium, andhas for .its 0 jectto provide means for assisting the incoming impulsesto expand or inflame said ined unu and artially sectional viewmyinventi'on, the-electric circuit being'in diagram;

13 is the explosive chamber rovided with the valves 14 and 1-5 and thein ct pipe 7. A localized circuit comprising the wire -17, battery 1 9,electro-magnet 20; wire 18, and adjustable contact 16, is in operativerelation to the valve 15. The explosive chamber'is provided with theterminal 21 in electrical conne tion with the terminal 11 of the trans-The terminals 8 and-9 are connected respectively to the wires 22 and 26.To these wires are. connected the secondaries 23 and 25, joinedtogetherthrouglr wire 24 and .this wire is grounded through 12.. Thesecondary 23 is provided with the primary 27 and the secondary'25 withthe primary 28. The operation of this part of thearrangement is asfollows; Normally,.an interru. ted or alternating current is assedthroug the primaries 27 and 28, 't ereby generating alternating orrapidly recurring.

impulses in 23 and 25. base impulses should not be sufficient to reducea spark between 8 and 9, but they s iould be of suf ficient'strength,.so as to enforce the impulse coming throu h 11 and going from 21 eitherto 8-01 9-, as t e case maybe. With the aid of this arrangement, it 18possible to so enforce the incoming impulses that the sameno matter iforiginally, too weak to produce the necessary spark ofv high temperaturecan be used to explode the as or other medium contained in the chem r13.

To raise the explosive medium, such as a 8%,. t0 temperature short ofthe explosive:
